Hello! I'm modeling an xlam wall with push over analysis. I've to implement the friction between soil and wall through a friction isolator. I've followed this procedure :
1 creation of a new link 'friction isolator' with u1 and u2 non linear degrees of freedom
2 I use an high stiffness for u1 to represent the soil. In fact it's a gap element and so it has an infinite resistance to compression.
3 I write 0 in u2 stiffness (is it wrong?) and 0.4 in friction coefficient.
4 I design friction isolators as one-joint link and I put them on shell nodes.
Is it the right procedure?
